LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 564,992, dated August4, 1896.

Application filed March 2,1896. Serial No. 581,541. (No model.)

To all whom it Til/(Ly concern.-

Be it known that I, JOSEPH GREGORY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and use ful Lamp-Burner, of which the following is aspecification.

This invention aims to equip lamp-burners with a flame-extinguishingdevice which is operated automatically by the provisions employed forraising and lowering the wick, thereby obviating the necessity forblowing out the light when it is required to extinguish the same; tohave the extinguisher fit close I 5 against the end of the wick-tube soas to prevent siphoning the oil; to dispose the extinguisher whereby itwill remove the charred or burned end of the wick, thereby keeping thelatter in condition so as to insure a clear and extended flame, and'tohave'the parts so disposed that the wick-controlling provisions can beoperated without interference on the part of the extinguisher, all aswill appear more fully hereinafter.

For a full understanding of the merits and advantages of the invention,reference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various 0 changes in the form,proportion, and the ininor details of construction without departingfrom the principle or sacrificing any of the advantages thereof, and toa full disclosure of the invention an adaptation thereof is 3 5 shown inthe accompanying drawings, in

which Figure 1 is a perspective view of a lampburner having theinvention applied thereto. Fig. 2 is a detail view showing theextinguisher thrown to one side of the wick-tube. Fig. 3 is a viewsimilar to Fig. 2, showing the extinguisher closing the end of thewicktube. Fig. 4 is a detail view of the extinguisher and thewick-raiser.

Corresponding and like parts are referred to in the followingdescription and indicated in the several views of the drawings by thesame reference-characters.

The lamp-burner illustrated is of the ordinary type, and comprises thewick-tube 1,

gallery 2, and the wick-raising shaft 3, the latter having the usualbutton or knob i at its outer end and the spur-wheels 5 near its innerend to engage with and operate the wick.

The extinguisher comprises a plate 6 and a lever 7, the plate beingoblong and conforming to the shape of the wick-tube in crosssection, soas to extend over the latter and arranged to secure a close fit againstthe end of the wick-tube, so as to prevent the escape of the oil eitherby siphoning or by capillary attraction. The lever 7 is a spring-wire ofproper length, and comprises a vertical arm 8, a horizontal portion 9,and a pendent arm 10, which is adapted to engage with a plate or disk11, secured upon the shaft 3. This lever 7 is fulcrulned to the gallery2, preferably by having its horizontal portion 9 secured to the galleryby short binding-wires 12, the latter passing through adjacentperforations of the gallery and extending over the horizontal portion 9and having their ends twisted together. These bindingwires 12 fix theposition of the lever and hold it in working relation. The pendent arm10 extends through a perforation of the gallery, thereby preventing anylongitudinal movement of the lever after the parts have been assembled.The wire from which the lever is constructed is sufficiently elastic toprevent straining of the parts or undue pressure of the plate 6 againstthe side of the wick or the end of the pendent arm 10 against the plateor disk 11.

The plate or disk 11 is secured upon the wick-shaft 3 so as to turntherewith, and is disposed so as to engage with the terminal portion ofthe pendent arm 10, whereby the latter is moved to throw theextinguisher into or out of operative relation, and so as to hold it ineither of these two positions. The plate or disk 11 is notched orrecessed, as shown at 13, to receive the terminal portion of the pendentarm 10, whereby the latter is positively actuated, and the walls of thisnotch or recess flare in opposite directions to admit of the terminalportion of the arm 10 riding out of the notch or recess upon turning theshaft 3 after the extinguisher has been moved in the desired direction.As shown, the edge portion of the plate or disk is notched, and thelower portion of the arm 10 is bent at 14 to extend across the path ofthe plate or disk 11, so as to drop into the notch when the latlerassumes a position opposite the terminal of the said arm 10. The numberand posi tion of the notches or recesses may be varied at will, and anypart the equivalent of the notch can be resorted to for moving the leverwhen the shaft 3 is operated, which will serve to throw the extinguisheracross the end of the wick-tube or away therefrom. Upon turning theshaft 3 so as to lower the wick the lever 7 will be actuated and movethe plate 6 toward the wick-tube, and after the wick has passed withinits tube the plate 6 will spring over the end of the wick-tube and closethe latter, thereby completely extinguishing the flame. It will be seenthat the inner or front edge of the plate 6 will press against the sideof the wick with sufficient pressure to remove the burned or charred endthereof prior to the wick moving within its tube. The spring action ofthe wire from which the lever 7 is constructed admit-s of this result,which could not be attained if the lever 7 were made of heavy or stoutwire devoid of elasticity. \V hen turning the shaft 3 in a direction toelevate the wick, the extinguisher will be turned aside, so as not tointerfere with the light or the wick. Obviously when the terminalportion of the pendent arm 10 is in en gagement with the plate or disk11 between its notches or recesses the said shaft can be turned ineither direction for the purpose of raising and lowering the lightwithout extinguishin g it, as will be readily comprehended, and for thisreason the notches or recesses should not be provided in too greatnumber or located at short distances apart.

Having thus described the invention, what is claimed as new is- 1. In alamp-burner, the combination with the wick-raisin g shaft, of anextinguisher comprising a spring-arm havinga lateral extension, and aplate or disk secured upon the wick-raising shaft to turn therewith atall times and adapted to engage with the said lateral extension andpositively actuate the extinguisher and hold it in the adjustedposition, substantially in the manner and for the purpose set forth.

2. In a lamp-burner, the combination with the wick-raising shaft, and anextinguisher, of a plate or disk secured upon the wickraising shaft soas to turn therewith and having a notch or recess having flaring sidesand adapted to engage with and positively actuate the said extinguisherand hold it in the adjusted position, substantially as and for thepurpose set forth.

3. In a lamp-burner, the combination with the wick-raising shaft, and anextinguisher having a pendent spring-arm, of a plate or disk securedupon the wick-raising shaft to turn therewith and having a flaring notchor recess to receive the terminal portion of the aforesaid pendentspring-arm to positively actuate the extinguisher in each direction, andadapted to admit of the said arm riding out of the notch or recess,substantially as and for the purpose set forth.

i. In a lamp-burner, the combination with the wick-raising shaft, and anextinguisher having a pendent spring-arm, of a plate or disk having aportion to make positive engagement with the extremity of the saidpendent spring-arm to throw the extinguisher into or out of operativerelation, and having a part upon each side of the said engaging portionto hold the extinguisher in the position into which it is thrown toadmit of the wick-raising shaft being turned in either direction withincertain limits without changing the position of the said extinguisher,substantially as and for the purpose set forth.

5. In a lamp-burner, the combination of a sprin g-wire bent to providevertical and pendent arms and an intermediate horizontal portion, thelatterbeing journaled to the gallery, and the pendent arm passingthrough a perforation therein,a plate secured to the vertical arm andadapted to fit close against the end of the wick-tube, and a plate ordisk secured to the wick-raising shaft and having a notch or depressionwith flaring sides to engage with the extremity of the pendent arm toactuate the latter positively, substantially in the manner and for thepurpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
